摘　　要：In view of the importance of dispersion agent,the amount of the crosslinking monomer and the diluent in suspension polymerization for the production of particle size narrowly distributed low-density stryene divinylbenzene copolymer microbeads(LDPS),their actions are preliminarily investigated in this paper.Experimental results indicate that when both the gelatine and polyvinyl alcohol(PVA)are used dispersion agents,the better effect is achieved,DVB is helpful to the formation of the lower density fine particles,the proportionof the DVB/St should be between 1:1-1.5:1.Compared with toluene,gasoline is the more effective diluent for the above target.
